The Hans and Roon meme stems from the vibrant fan community of the mobile game Azur Lane, specifically focusing on the intense personality of the ship girl Roon and her interaction with a fan-created version of the Commander named Hans. Roon is widely known for her 'yandere' traits—extreme affection coupled with a terrifying, violent side—while Hans usually represents the voice of reason or the victim of her overwhelming presence. The template is frequently used to illustrate scenarios where one party is intensely aggressive or obsessive while the other is visibly shaken or resigned. It has evolved from niche fan art into a versatile format for depicting any high-pressure or awkward social interaction where someone is clearly outmatched.
